' To all whom it may concern."

liquor is forcibly circulated through the dyeing receptacle, and thedirection of the flow of the liquor is capable of being reversed.

. An object of the invention is to provide a machine, wherein the dyeholding receptacle is of comparatively small proportions, and the meansfor circulating the'dye liquor'in said receptacle is located outside ofthe same and so connected thereto that the direction of flow of theliquor in the receptacle may be reversed.

A further object of the invention is to provide a dyeing machine of theabove character, with a perforated rotatable drum for holding thematerial to be dyed, which drum isalso provided with means whereby thedrum may be readily lifted from the receptacle, so that the drum may bereadily loaded and unloaded of the'material to be dyed.

-A further object of the invention is to provide a dyeing machine,wherein the receptacle for the dye liquor is formed with a laterallyprojectingframe having bearings for supporting the drum for the materialto be dyed when the same is lifted from the receptacle for the dyeliquor.

A further object of the invention is to provide a dyeing machine of theabove character, with a supply tank for the dye liquor, which'tank issupported above the level of the receptacle and connected thereto bypipes, so that the liquor may be discharged into the receptacle bygravity, and wherein said retaining tank is also connected to the dyeingreceptacle by suitable pipes which lead through a pump so that the dyeliquor may be forcibly returned to the supply tank, when desired.

These and other objects will in part be obvious and will in part behereinafter more fully described.

In the drawings, whichv show by way of illustration one embodiment ofthe invention, Figure I, is a plan view of a dyeing machine embodyingthe improvements. Fig. II, isa side elevation of the same. Fig. III,

is an end view, showing in dotted lines thedrumlifted from thereceptacle and placed on the laterally projecting supporting frametherefor. Fig. IV, is a vertical sectional view through the supportingbearings for the rotatable drum. Fig. V, 1s a sectional view on the lineV.V of Fig. IV. Fig. VI, is a detail sectional view on-the line VIVI vof F ig. IV, showingthe supporting bearing the ready circulation of thedye liquor.'

The drum is rotated by suitable gearing and is adapted to be lifted fromthe receptacle andplaced on a laterally projecting frame having bearingstherefor. The drum may be thus transferred to a position where it may bereadily loaded and unloaded. The dye liquor is circulated through thereceptacle by a pump, which is located outside.

thereof and this pump is connected to the receptacle by suitable pipes,which are so arranged and provided with valves that the flow of theliquor in the receptacle may be' reversed without reversing thedirection of the rotation of the pump.

There is provideda supply tank for the dye liquor situated either abovethe receptacle, so that it may be drained by gravity and connected withand filled from the retaining tank by the pump; -or below the tacle, asshown in the drawings, is open at the top. Attached to each side wall ofthe receptacle are supporting bearings 1 and 5. Each bearing consists ofa base plate, from which projects a U-shaped flange 6. The base plateand flange preferably extend to the top of the receptacle and the flangeforms a bearing support for a rotatable cage or drum 7. The drum 7 isformed with a central cylindrical section 8,.which is perforated. Endwalls 9, 9, are also perforated and the outer section on the wall 10, iscylindrical and is similarly perforated.

The material to be dyed is placed in the compartment formed between thecylindrical section 8, and the outer cylindrical section 10. Thecompartment formed by the inner and outer cylindrical perforatedsections 8 and 10, is provided with radial partitions 11, which, asshown in Fig. V, are six in number, although any other desired number ofpartitions may be selected. These partitions are likewise perforated.The outer cylindrical section 10, is made up of a plurality of hingedsections or doors which afford access to each compartment. The drum isprovided with an end plate 12, at each end thereof and this end platecarries a cylindrical projection 13, which serves as a bearing for thedrum or cage. This cylindrical projection is formed with a passage 14,therethrough. One of the end walls of the receptacle is formed with anopening 15, and the base plate 5, has a sleeve extending through saidopening on to which is threaded a collar 16. A supply pipe 17, extendsthrough this sleeve. The passage 18, of said supply pipe registers withthe passage 1A, in the cylindrical bearing projection for the cage ordrum. lVhile the pipe 18, is referred to as a supply pipe, it will beobvious that this pipe may be an outlet pipe. It will be noted that thispipe leads directly to the inner compartment formed by the cylindricalperforated section 8. The receptacle 1, is also provided with a secondpipe 19, which extends through the wall of the receptacle and is locatedat the extreme lower part of the receptacle. This pipe may be either asupply pipe or an outlet pipe, as desired.

The rotatable drum or cage 7 is formed at one end thereof with a gear20. A short shaft 21, is mounted in a suitable bearing in one end wallof the receptacle and this shaft carries a pinion 22, at its inner endwhich meshes with the gear 20. Said shaft carries a sprocket wheel 23,at its outer end which is adapted to be driven by any suitable drivingmechanism. It will be noted that this shaft 21, is located in ahorizontal plane passing through the axis of the drum. This permits thedrum to be readily raised from its supporting bearings. It will also benoted that the curvature of the bottom of the receptacle issubstantially the same as that of the drum, sothat only a comparativelysmall amount of dye liquor is necessary to completely submerge the drum.The drum is preferably formed with projecting lugs 24, each of which isperforated at 25, so that a suitable lifting mechanism may be connectedthereto for raising the drum from the receptacle. The receptacle is alsoformed with a laterally projecting frame 26, which is supported bysuitable legs 27. Spacing bearings 28, are mounted on the projectingframe 26, and these hearings are adapted to receive and support the drumwhen it is raised from the receptacle, so that the drum may be readilyloaded and unloaded.

The dye liquor is circulated through the receptacle 1, by a pump 29,which is of the ordinary rotating type, and this pump is driven by apulley 30. The pipe 19, extends to the pump 29, and is connected to thecenter thereof. A hand valve 31, is located in said pipe. The pipe 17,is connected through a coupling 32, with the outlet or discharge of thepump 29. A hand valve 33, is located in said pipe 17. A pipe 3 1, isconnected with a pipe 17, between the hand valve 33, and the receptacle,and this pipe is also connected with the pipe 19, between the hand valve31, and the pump 29. A pipe 35, is connected to the coupling 32, and tothe pipe 19, between the hand valve 31, and the receptacle. A verticalpipe 36, extends upwardly from the coupling 32, and this pipe isconnected at its upper end to a retaining receptacle 37. A branch pipe38, leads from the bottom of said receptacle and connects with the pipe36. A hand valve 39, controls the branch pipe 38, while a hand valve 10,controls the vertical pipe 36.

Let us suppose thatv the receptacle is entirely empty and it is desiredto supply the same with the dye liquor which is retained in the supplytank 37. The valves 39, 40 and 33 are opened and this allows the dyeliquor to pass by gravity through the pipes 38, and 17, into thereceptacle. hen the receptacle is supplied with sufficient dye liquor,the valve 10, may be closed and also the valve 39. The material to bedyed is placed in the cage or drum 7, which is inserted in thereceptacle and is rotated by the mechanism above described. If thevalves 31, and 33, are open and the hand valves 41, and 42, locatedrespectively in the pipes 34:, and 35. are closed, the pump will drawthe liquor from the receptacle through the pipe 19, and force it intothe receptacle through the pipe 17. The dye liquor entering thereceptacle through the pipe 17, will be directed to the center chamberof the cage or drum 7 and will pass out through perforations therein andthrough the perforations in the end walls and the outer are opened. Thepipe 3 1', will then become,

the receiving pipe forthe pump'29, drawing the liquor through thepassage 18, and,

delivering the same to the pump. The pump will in turn deliver the dyeliquor through the pipe35, and the pipe 19, to the receptacle therefor.When it is desired to remove the dye liquor from the receptacle, thehand valves 33, 41 and 42 are closed, while the hand valves 31, and. 40,are opened. The rotation of the pump will now draw the dye liquorthrough the pipe 19,- anddischarge the same through the pipe 36, intothe upper end of the retaining tank therefor. f

Although we have illustrated the supply tank 37, at a level above thatof the receptacle 1, we do not wish to be'thus limited, since therelative position of these two elements is immaterial, and may bealtered to suit individual conditions, and the pump 29, might be usedjust as readily to force the liquor into the receptacle 1, instead ofout of the same, as above described.

It is obvious that minor changes in the details of construction andarrangement of parts may be made without departing from the spirit ofthe invention, as set forth in the appended claims.

Having thus described our invention, we claim:
